This is only bypassing a protection that no other consumer processors have anyway.

Basically each pointer has magic number in order to work and so an exploit only has a 1/16k chance of working and this protection is what's bypassed. You still need an exploit and access to use it just like on any other computer.

So M1 is just the same safe as an Intel/AMD not extra safe.

edit: if you want an example of a real boneheaded mistake Google created SPDY aka HTTP/2 and put it in their browser with it compressing private and public header data at the same time, which means any javascript could read all the cookies you had from any site. Afaik the ones behind it were not diversity hires but certainly were white knight fedora wearing idiots; they were so eager to destroy privacy with SPDY/HTTP 2 that they accidentally destroyed it too much and had egg on their face looking like freshman comp sci.
